Following the results of an in-depth study of 4,500 patients in the recovery period following knee and hip replacement surgery, there is robust evidence to support the theory that an enhanced recovery plan is the best approach to a successful recovery.

What is enhanced recovery?

An enhanced recovery plan is one where patients will be recommended a multimodal approach, involving behavioural, pharmacological, and procedural modifications to the ‘standard’ approach to rehabilitation.

The research looked at 4,500 patients, 1,500 of whom were treated with the enhanced approach, while the remaining 3,000 had standard care. The results were positive, suggesting that the enhanced approach is likely to result in faster recovery, with fewer requirements for medical interventions following the surgery.

The areas where benefits to the patient were seen are as follows:

Length of hospital stay

Mortality

Perioperative complications (for example, the need for a blood transfusion following surgery)

Overall satisfaction felt by the patient regarding their experience and treatment

Collaborative working methods

We are hearing more and more about the benefits of different parts of the health care system working together, taking a joined up, more collaborative approach to patient care and recovery. This way of working is cited as being fundamental to the success of an enhanced recovery approach, as explained by the US National Library of Medicine National Institutes of Health “a prerequisite for the success of these techniques is a multidisciplinary collaboration between patients, surgeons, anaesthetists, physiotherapists, occupational therapists, and nursing staff.” This approach to enhanced recovery is used widely across the NHS, with ambitious plans to continue pushing this until the health service is fully integrated by 2018.

As a result, the NHS is working effectively to improve recovery following joint replacement surgery. The challenge is to get processes like this working as well in private clinics, as this method (and ability to offer such joined up care and service) is currently inconsistent. Mr Simon Bridle favours this approach and recognises the benefits, so patients treated in his care will benefit from a multimodal design to their recovery plan.

As with all operations and the subsequent recovery process, the most important factor is the best possible rehabilitation for the patients. Getting them back to normal as soon as possible is of the utmost importance to medical professionals, whether working in the public or private sectors.

Fortius Joint Replacement Centre

Mr Bridle and his colleagues at Fortius Clinic have worked with the BUPA Cromwell Hospital to develop an evidence based Enhanced Recovery programme, based at the BUPA Cromwell, to ensure the best treatment and outcome for our patients.

As Mr Bridle will explain to any patient he is treating, an effective, multimodal rehabilitation plan and initiatives that reduce the risk of post-operative complications are at the forefront of his approach to patient care.

When you’re considering joint replacement, it is important to choose the best surgeon for the job. So how do you go about this? You will first want to read around the procedure so that you fully understand what you’re signing up for, and then you’ll want to start researching where you can have the operation and exactly who will be responsible for undertaking it.

Look at the surgeon’s qualifications and professional memberships

Orthopaedic surgeons in the UK will have undergone full medical training and then an additional 4 to 5 years residency programme in an orthopaedic surgery. After this lengthy training period they will qualify as a junior orthopaedic surgeon and will begin practicing. Some surgeons will choose a subspecialty which they will focus on, and this will require a further one to two years training.

Obtaining membership of professional associations

Many professionals will also choose to join relevant professional membership organisations. Many will join these while studying and hold membership of different grades throughout their career.

Mr Bridle holds membership of two professional associations for joint replacement specialists, the British Hip Society and the British Orthopaedic Association. The British Hip Society promotes training, education and research to ensure the very best care for patients who are experiencing hip related conditions. Similarly, the British Orthopaedic Association offers care for patients and support for trauma and orthopaedic surgeons in the UK.

Membership organisations such as these offer services such as training, support and continued professional development (CPD). They also regulate their members to ensure a high quality of service provision. Orthopaedic surgeons such as Mr Bridle will typically list their professional memberships on their website, so when you’re researching surgeons, look out for the logos and feel free to look up the organisations to read more about what is expected and required of their members.

National Joint Registry

All hip and knee replacements in England are now recorded in this registry (the NJR). This allows analysis of how well different types of joint replacement and individual surgeons are performing. An individual surgeon report is published on an annual basis, to include the number of procedures performed, the type of implants used and some results. The surgeon is provided with an even more detailed analysis, to indicate how well patients are doing, to help them improve their practice. This represents an extremely important set of data to help improve quality.

Ready to book a joint replacement consultation?

Once you have done your research and think you’ve found a surgeon you are comfortable with, the next step is to book a consultation. This is an important opportunity to meet with the surgeon, get to know and to talk in detail about what is troubling you and what you would like to achieve. This is a great chance to ask all the questions you may have, so it is advisable to write a list so that you don’t forget anything important.

To give you an indication of the types of questions you might consider asking, these are some of the things patients will typically ask at a consultation:

How long have you been practicing for?

How many times have you performed the operation I am interested in?

Can I speak to any patients you have operated on previously?

What is your personal complication rate for procedures of this type

What options do I have for this procedure and which is best for me? And why?

How long will the operation take?

How long is the recovery process and what can I expect during this time?

When will I be able to go back to work?

When will I be able to drive?

Aches and pains in the joints – particularly knees and hips – as you get older are something that we all expect and many of us choose to live with. Depending on the cause of hip pain, this is sometimes an acceptable choice, but more often than not it could be delaying treatment for a more serious condition.

With the amount of information available to read online, sometimes people will ‘self diagnose’ – and this can be risky. Sometimes even expert medical professionals can misdiagnose, so it clear to see that its very easy to make the wrong assessment when reading up online about what is causing your pain and discomfort. Often conditions share similar symptoms, and an expert assessment is required to ensure it is diagnosed correctly.

For people suffering with painful hip joints, two conditions that share similar symptoms are bursitis and arthritis.

Understanding bursitis

A bursa is a pocket of fluid, which helps lubricate movement when a tendon runs over a bone. Bursitis is the name given to a condition where this pocket of fluid becomes inflamed. This can occur when the area is exposed to unexpected pressure or repetitive stress.

When the bursa becomes inflamed, this causes pain and tenderness over the site of the bursa. In the hip the trochanteric bursa is most often involved and patients have pain over the side of the hip bone. Treatment is initially with physiotherapy and an exercise programme to strengthen the pelvic and core muscles and some patients will need a steroid injection.

Understanding osteoarthritis

Osteoarthritis is the most common form of arthritis and occurs in around one in three people aged 45 and over, and in almost half of people aged 75 years and over. It is a degenerative disease which affects the joints by wearing and breaking down the cartilage around the joints. The hips and knees are often affected by this form of arthritis. If left untreated, it can completely wear away the cartilage around the joints, which is extremely painful and will have a significant impact on mobility.

Getting the correct hip pain diagnosis

When assessing hip pain, experts will be looking for clues to help with diagnosis. Things they will be considering are issues such as the specific area where pain is greatest (for example, bursitis often generates pain on the outside of the lower hip whereas osteoarthritis causes greater pain in the bottom, thigh, groin or actually within the centre of the hip itself).

Another thing they will be looking for is what generates the most pain. With bursitis the pain will feel worse when pressure is applied, for example lying on the side in bed, whereas with osteoarthritis the pain will tend to occur with weight bearing and hip movements. X rays are often helpful in identifying arthritic joints, whereas an MRI scan is likely to be needed to confirm bursitis

Seek an expert opinion

The important thing to remember is that if you’re experiencing any form of hip pain it is crucial to see a specialist sooner rather than later, to arrange the appropriate tests and investigations. The correct diagnosis of whatever is causing your hip discomfort is the first step on the road to treatment – and hopefully recovery. The longer you live with undiagnosed hip pain, the greater the risk that you will be doing more permanent damage to your joints, muscles or cartilage.

If you have discomfort in the hip area and have not yet seen a specialist, book an appointment to see a knee and hip replacement specialist like Mr Simon Bridle who will be able to assess your situation and recommend the most appropriate next steps.

As a knee and hip replacement specialist, Simon Bridle is always keeping abreast of developments within the industry that could benefit his patients. One area that is developing and gaining a lot of attention recently is that of stem cell research, and the benefits this could bring to healing patients who are in the early stages of hip and knee problems.

There are thousands of people each year who develop osteoarthritis in their knee or hip joints, and it can be a painful, debilitating condition, causing the joints to stiffen and be sore and tender. Although there are treatments available such as total knee and hip replacements, treatments for the early stages of this condition vary in effectiveness, as they can only really help patients deal with the condition, rather than reverse the problem or restore the worn connective tissue around the joints.

Understanding stem cell research

Stem cell research is something that a lot of people have heard about, yet many people still have lots of questions about it. What is it? How does it work? Is it available now?

Stem cells are human cells that are able to develop into other types of cells as they are forming. This means that they are being explored as being able to offer healing properties, as they could potentially create more cells that can be used beneficially in a damaged area of the body. The exciting fact about these cells is that when a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell.

This research could mean that people who are suffering with the very early stages of knee or hip joint arthritis may be able to help lessen or reverse the progress of the condition. It is important to recognise the limitations of stem cell treatments, for example it is likely to be that younger patients with isolated small areas of articular cartilage damage are most likely to be those who could benefit from stem cell treatment as a means of delaying the need for joint replacement surgery.

The treatments that are undergoing research at the moment involve extracting mesenchymal stem cells (MSCs) and platelet-rich plasma directly from the patient. As the cells come from the body, the expected benefit is that the patient’s immune system should not reject the new cells.

Patience required

There are companies that are already talking about “regenerative” or “bio-restorative” medicine as an alternative to joint-replacement surgery, but Mr Bridle warns that although these technologies sound exciting, they are still in their medical infancy. It is likely to be many years before this kind of treatment could be available more widely.

Nevertheless, it is through research such as this that we keep progressing medical knowledge, so although this is still in the early stages of research at the moment, this is likely to be something that we hear a lot more about in years to come.

If you’re considering a joint replacement it is important to understand what will be happening to your joint and what the old bone joint will be replaced with. By understanding the different options available you can make a fully informed decision about which option is best for you.

The bearing is the moving part and in an artificial joint this will inevitably produce debris, which over time can damage the tissues and cause the hip to loosen. Younger patients will tend to be more active and this can increase the amount of debris being produced, which will build up over time.

The choices available

A lot of effort has gone into developing bearings which are more wear resistant, which will hopefully last longer. For younger patients, Mr Bridle suggests the choice is between “ceramic on ceramic” and “ceramic on polyethylene” replacement joints. Both these combinations allow patients to get back to high levels of physical activity if they want to.

Ceramic on ceramic joint replacements are very hard and very smooth, which means that they are a very durable, wear resistant material, with very little friction, allowing a degree of lubrication between the moving parts. Concerns about ceramic on ceramic bearings include the risk of fracture of the material, which can be disastrous (albeit this is a very small risk), along with occasional reports of the joint squeaking, which can be quite disconcerting! Ceramic on ceramic is the most expensive bearing option.

Polyethylene has been used as a bearing in hip replacements for many years. Great efforts have gone into improving this material over the years, as we realised that this was an important source of wear debris, causing hip replacements to fail. Modern polyethylene is far more wear resistant, as we have found ways to make it more durable. In addition polyethylene acts as a ‘shock absorber’ far better than ceramic.

A ceramic on polyethylene bearing combines the advantages of ceramic, which is used for the head component (ball), with those of polyethylene which is used for the socket. Mr Bridle recommends this combination for most of his patients. Testing these bearings in the lab has shown an extremely low wear rate and recent publications confirm that this is reproduced in patients who have had these bearings implanted. We are optimistic that this combination will last just as long as the alternatives, with none of the possible complications.

Making an informed choice

When you’re considering joint replacement you will be able to discuss the pros and cons of the different materials available and make the best choice for you. There is no such thing as a ‘one size fits all’ approach when it comes to joint replacements. Your consultant will be able to offer advice based on your own unique situation, and will be able to answer any questions you have.

Factors such as the age and weight of the patient will need to be discussed and considered, as will the type of lifestyle. These are all important to consider when selecting the most appropriate material for any replacement joint. If you are experiencing joint pain and are considering surgical options, book an appointment today to speak to Mr Bridle so that you can begin exploring different options sooner rather than later.

When opting for any form of surgery one of the first questions patients will need to understand is how long the operation will last for. It is an important consideration when weighing up the pros and cons of whether or not to opt for a surgical solution to the problem you’re suffering with, as redoing the hip is a very major operation.

Hip replacements are done in patients of all age groups and increasingly in younger patients, so knowing how long the hip will last is a major factor in deciding whether to have an operation.

Long-standing history of hip replacements

Hip replacements have been practiced by surgeons for decades, so there is a lot of data available to help answer this question. Hip replacements were first performed in the UK back in the 1960s, and due to its success rate this has become a very popular operation. In England and Wales there are now approximately 160,000 total hip and knee replacements performed each year.

According to the results of a 40-year observational study of patients at the Mayo Clinic in the USA who have had their hips replaced, looking at 2000 patient cases, the hip failed and required revision in only 13% of these.

This varies somewhat by the age of the patient, so the report helpfully breaks this down by age group to give a clearer indication of how this differs by age:

Patients under 50: One in three required a revision

Patients aged 50 to 59: One in five required a revision

Patients aged 60 to 69: One in ten patients required a revision

Patients aged over 70: One in 20 patients required a revision

So there are definite differences by age group, and this will be affected by factors such as lifestyle choices (how active or sedentary the patients are following the operation), how much stress the new joint is put under, how well the recommended physiotherapy is adhered to following the operation and the overall health and well-being of the patients.

Practice makes perfect

It is an important conclusion that the majority of patients, even in the younger age group will never need another operation on their hip.

The other consideration is that owing to the continued practice of this operation, hip replacements are getting better and more effective over time. A hip replacement operation performed now will benefit from greater knowledge and understanding of surgeons now, compared with one undertaken 40 years ago, so modern hip are likely to do even better than these figures.

The Exeter hip system

Joint replacement specialist Simon Bridle favours the “Exeter femoral stem” model of hip replacements, which are collarless polished tapered cemented hip stems, first developed at the University of Exeter. At the time of its design, scientists were grappling with how to best fix the stem to the bone.

Because the Exeter design is polished and collarless, it allows very good transfer of stress from the stem to the cement and this means that the bone is loaded and the cement is protected and allowed to last for a long time.

The authors of another Bone and Joint Journal article found that 99% of the stems were still well fixed and working at 22.8 years from the replacement. They look at the X rays and found that a “radiological review showed excellent preservation of bone stock at 20 to 25 years, and no impending failures of the stem.”

In summary, the approach of conducting total hip replacements using an Exeter stem is one that has been trusted by experts such as Mr Bridle for many years and patients can have confidence in this approach. For more information or to book an appointment, please contact us.

For anyone who is considering a hip replacement, it is likely that you’ll be reading around the subject and making sure that you’re up to speed on what to expect from the procedure.

There has been a flurry of news recently about the speed and efficiency of anterior hip replacements, with stories about patients having this operation and being discharged later that same day, but this has some consultants concerned.

What is an anterior hip replacement?

This type of hip replacement is designed to cause minimal damage to the tissue and muscle that surrounds your hip joint. It is a very different approach to total hip replacements, requiring surgeons to learn a different technique.

Surgeons work by making a small incision on the front of your hip (rather than the back or side, which is more typically the case with total hip replacements).

Back to a more effective approach

Joint replacement specialist Simon Bridle recognises that hip replacement technologies have progressed significantly over time, although it is his belief and recommendation that approaching the joint from the posterior (back of the joint) is the safest and most effective means of undertaking this operation.

Although the posterior approach requires an incision through the gluteus maximus muscle, it requires the fibres to be separated, not actually cut. A small group of muscles called the short rotators are cut off the back of the hip and repaired back at the end.

There is no evidence that this approach results in any detectable muscle weakness in the long term. Mr Bridle believes that the anterior approach does not provide tangible advantages in terms of limiting the amount of pain or discomfort experienced by the patient, or to the overall effectiveness of the operation.

With modern anaesthetic techniques and pain relief many patients are leaving hospital in 2 or 3 days after a posterior approach, with rapid rehabilitation, so the short term potential benefits of an anterior approach are probably overplayed, with no evidence of any long term benefit at all.

Concerns with the anterior approach

In fact, the anterior approach raises some significant concerns for surgeons such as Mr Bridle. By making the incision at the front it is much closer to the lateral cutaneous femoral nerve (this runs along the front of the hip and supplies the skin on the side of the thigh).

In some cases patients have reported feeling numb in the top of their thighs following an anterior hip replacement, as a result of damage to this nerve and this can be very troublesome. The anterior approach is more difficult, increasing the risk of other surgical problems. It has been shown that it takes surgeons a long time to learn how to do it well.

Special implants have been developed to make it easier, but these often have no track record, so we don’t know how well they will do. All these issues are avoided with a conventional posterior approach.

Best foot forward

As with any medical professional, surgeons will select and recommend the treatments that they believe are best suited to their patients’ needs and requirements. Although a shorter stay in hospital – which an anterior hip replacement may offer – may be attractive, when the overall risks and benefits are weighed up, it does not fare as favourably.

Mr Bridle believes that the posterior approach offers a safer and more reliable technique for his patients.

It is not unusual to wish to put off major surgery for as long as possible. As well as having concerns about the procedure itself and the associated risks, many patients are apprehensive about the necessary downtime after the surgery and the upheaval that will bring.

With joint replacement surgery in particular, there is often a desire to delay the procedure, as London hip and knee surgeon Mr Simon Bridle knows only too well.

When a patient has been suffering with joint pain for some time, it may seem that putting off surgery by a few months will only be extending the current suffering. But are there unseen risks involved in delaying a hip replacement procedure?

Risks of delaying total hip replacement

It is fair to say that delaying joint replacement surgery by a few months will probably not create major problems. However, it is important to be appraised of all the facts when considering having – or delaying – any form of surgery, and there are some complications associated with a prolonged postponement of total hip replacement surgery. It is always a good idea to speak to your surgeon before making any major decision around hip replacement surgery.

Problems with the joint itself

Depending on your particular hip problem, there is a possibility that the problem will worsen over time. This can mean that a deformity of the joint progresses – although this is generally a gradual process, that joint stiffness increases, or that the muscles surrounding the joint become weaker as you are using your hip less. Sometimes progressive damage to the joint makes the surgery more complex and recovery longer.

Compensatory problems

When you have pain in one hip, the natural tendency is to put more pressure on other joints. There is very little clinical data to support the theory of compensatory joint problems, but anecdotal evidence is common: many patients who visit Mr Simon Bridle’s London hip clinic experience back problems and pain in other joints, as well as the affected hip. The longer surgery is delayed, the greater the chance that this pain, as well as the pain in the affected hip, will increase.

General health problems

Increasing levels of disability with progressive hip arthritis leads to a more sedentary existence and will have an effect on patients’ general health. They tend to lose physical fitness and put on weight and this can have an effect on the heart and lungs, as well as other body systems. Prolonged use of pain killers can also have an effect on the kidneys. All this can increase the small risk of complications associated with surgery.

Can I avoid or delay hip replacement surgery?

The study showed that patients who took part in an exercise programme for one hour, twice a week over a twelve-week period, were 44 per cent less likely to need hip replacement surgery in later life than their peers who did not exercise.

If you have already been told that you need hip replacement surgery, it is unlikely that exercise will avoid the need for the operation. However, there is no doubt that low impact exercise will improve patient’s physical fitness, which can only be a good thing when approaching major surgery.

To find out more about your own situation and whether there is anything that can be done to delay surgery, why not book a consultation with London hip surgeon Mr Simon Bridle today.

Two studies on the effects of joint replacement have hit the news recently – one, from the University of Oxford, examined the long term benefits and limitations of knee replacement surgery.

The second study, which gained a lot of media coverage, came from the University of East Anglia and looked at activity levels in patients before and up to one year after hip replacement surgery.

Studies like these are very useful to help improve the practice of orthopaedic surgeons, such as London hip and knee surgeon Mr Simon Bridle, but there is often a danger when they are reported in the mainstream press that the results can be taken out of context.

Here, we will look at each of these studies objectively and examine the results in more detail.

The knee replacement study

This piece of research has not received much general press coverage, but was reported by Arthritis Research UK, who have provided a neat summary of the results for patients.

The study looked at the long term benefits of knee replacement surgery, as well as investigating factors that can affect the effectiveness of treatment. A group of 1,980 people receiving total knee replacement surgery were assessed by the research team both before the procedure and again ten years post op, to find out more about their individual outcomes.

Researchers found that both pain and function of the knee joint improved over the ten-year period, although pain significantly more so, showing that while knee replacement surgery is shown to be effective in relieving knee pain, the less satisfactory functional results suggest that improvements in implant design and surgical techniques will further improve results.

A number of factors were identified which were associated with less good results. Patients who are overweight and who have had previous operations on their knee tend to do less well other patients.

Consultant hip and knee surgeon Simon Bridle welcomes studies such as these, which allow him to give more accurate information to patients considering knee replacement surgery, as well as providing a catalyst for the improvement of surgical techniques and technology.

The hip replacement study

This study, conducted by researchers from the University of East Anglia, is equally useful to orthopaedic surgeons like Mr Bridle. Unfortunately, however, media coverage such as this piece in the Sun has misled the general public and caused concern amongst many hip replacement patients.

The study itself looked at the activity levels of patients, both before and up to one year after hip replacement surgery. Rather than researchers assessing patients themselves, this paper was a review of 17 different studies on the subject, carried out between 1976 and 2016.

Having analysed the results of all the different studies, researchers found that there was “no significant statistical difference in physical activity levels before and up to one year after unilateral primary total hip replacement.”
Does this mean hip replacement doesn’t work?

Articles like the one in The Sun have claimed that the study shows that hip replacement surgery is unnecessary. However, it is always important to analyse all aspects of a study.

As Mr Martyn Porter, Medical Director of the National Joint Registry, explains:

“Joint replacement surgery offers significant benefits – getting patients back to their chosen lifestyle sooner, free from pain and with improved mobility. Of 91,760 patients surveyed in 2013, 92% described themselves as being either ‘excellent’, ‘very good’ or ‘good’ six months after surgery.
“The main reason for doing hip replacement is to improve pain and there is overwhelming evidence that hip replacement is a wonderful success at improving pain dramatically for the vast majority of patients.”
Mr Porter goes on to say that the overwhelming majority of hip replacement patients report a marked improvement in functionality after the procedure, something that is reflected in Mr Bridle’s own London hip replacement clinic.

If you’ve been struggling with the discomfort and loss of mobility associated with arthritis of the hip and knee, then you may be contemplating a joint replacement procedure. Your choice of orthopaedic surgeon to carry out this surgery is probably the most important decision you will make.

There are four important factors you should take into account when choosing your joint replacement surgeon

1. Experience

How long has your surgeon been practicing? Mr Bridle has been a Consultant Orthopaedic Surgeon since 1994, specialising in hip and knee replacement and revision surgery. He has set up a hip and knee Multidisciplinary Team to deal with patients with hip and knee problems. In addition, he has been active in NHS management, holding important roles such as Lead for Orthopaedics, Clinical Director for Surgery and Clinical Director for Major Trauma at St George’s Hospital, London.

2. Expertise

How many knee or hip replacements do you perform a year? Choose a surgeon who regularly performs hip or knee replacements and can discuss their results with you. Over the last ten years, Mr Bridle has performed nearly 1000 primary hips and 500 primary knee replacements and specialises exclusively in this form of surgery.

3. Choice of prosthesis

It is very important that the prosthesis we put in lasts a long time, avoiding the need for complex revision surgery. There are a very large number of hip and knee implants available on the market. Hip and knee implants are rated by ODEP, with the long-term results available through the National Joint Registry. Mr Bridle uses only the best-rated implants, with the best long-term survival. More details on this are available on the website.

4. Complication rate

There are a number of rare, but important potential risks and complications associated with joint replacement surgery, including infection and dislocation, and your surgeon should be able to provide you with their rates of incidence. Mr Bridle has a very low complication rate in his own primary replacement procedures and his experience and expertise is such that he is often called upon to treat complex revision procedures. This is dealt with in more detail on the website.
